土地退化评价方法的探讨──以辽西北农牧交错带彰武县北部为例

A Method of Land Degradation Assessment in the Inter-distributing Area of Farming and Pasturing of Northwestern Liaoning Province

以辽西北农牧交错带彰武县北部几个乡镇为例探讨了土地退化评价方法。研究结果表明,根据土地类型所处的土地生态系统的演替阶段来判定土地退化程度,是目前比较简便而又切实可行的土地退化评价方法。该方法具有信息量丰富、方便快捷、比较准确等优点。

We took Zhangwu County in the northwest area of Liaoning Province as a case to study the method of land degradation assessment in the inter-distributing area of farming and pasturing. The results showed that it was a simple and practical method,which was based on the ecosystem succession stage of land types to assessment land degradation.And the ecosystem succession stage of land types could provide more information, which made the process of land degradation assessment more simple and more precise.
